After trying a lot of different anti-spam modules with Drupal 8, the best thing I’ve ever done to reduce comment spam is to go to the Drupal admin /admin/structure/types/manage/blog/fields URI, click Edit on the Comments field, and then select the “Anonymous posters may not enter their contact information.” Since I chose that option two days ago I’ve only had one spammy comment show up in my approval list. That field gave spammers a simple way to enter a URL, and without it, the spam seems to have dried up.
